Logo and Stationary Design

I would like you to design a Logo and a corporate identity package (Business Card, Letter Header, envelopes, tri-fold brochure, post card..) The design is for children's clothing store. So kids content and colors should be used, colors will be provided after the project won. I want something like a character to be derived from the name I provide.

I want you first submit to me 4 different sample designs with watermaks. If I like one of them, I will select you immediately, and I will send payment to escrow. Once you finish and submit all documents (source and jpgs), letterhead should be in Microsoft format, all documents must be editable, I will release the payment ony after the printing people will approve the documents.
